1. A system for providing gas turbine engine condition feedback, comprising:

  • a sensing assembly for sensing a temperature at a plurality of locations in a gas stream of a gas turbine engine and for generating a plurality of temperature signals corresponding to the temperatures sensed at the plurality of locations, the sensed temperatures providing a temperature distribution profile of the gas stream, a signal processor assembly for receiving and comparing the plurality of temperature signals from the sensing assembly, and for generating a warning signal when the difference between a maximum temperature and a minimum temperature is greater than a predetermined acceptable delta value, and an alert indicator assembly for alerting a human upon receiving a warning signal from the signal processor assembly.
